HDB main door replacement involves the door leaf, frame, hardware and its relationship with the entrance. First establish the requirements that apply to your flat, including whether a fire-rated assembly is required. Then choose the appearance and operating details.
A supplier's generic door package should not replace an assessment of the actual entrance.

1. Establish the applicable requirement
Ask the contractor to check the entrance against current HDB and relevant fire-safety guidance. HDB distinguishes replacement situations, including fire-rated and non-fire-rated main doors. Do not decide from a neighbour's installation or a rule repeated on social media.
Record the applicable requirement and any permit responsibility before choosing a product.
2. Assess the leaf and frame together
Have the existing frame measured and assessed for condition and compatibility. A door-leaf replacement and a complete door-and-frame replacement are different scopes. Ask what removal, fixing and making good are needed.
Do not assume a decorative surface can conceal a frame problem or that any new leaf can be combined with a retained frame.

3. Confirm the specified assembly and documentation
Where a fire-rated door is required, ask for the documentation applicable to the complete proposed arrangement, including relevant accessories. Check the actual selected product and installation. A marketing phrase such as solid wood does not establish fire performance.
Keep the supplier's certification and product references with the order rather than relying on the showroom's verbal assurance.
4. Resolve the lock and closing arrangement
Select the handle or digital lock with the door supplier before drilling or fabrication. For fire-rated doors, have the relevant certification and compatibility checked against current SCDF requirements. Confirm how the door closes and latches in normal use.
An attractive lock should not be treated as a harmless accessory that can always be added later.

5. Test the entrance in use
Draw the door, gate, foyer cabinet and nearby furniture in their operating positions. Check how someone carries shopping or moves a suitcase through the opening. Keep the common-area and escape-route requirements in the assessment.
Avoid a storage layout that works only while the door remains permanently open.
6. Coordinate floor levels and thresholds
Tell the supplier about proposed flooring changes before final measurement. Ask how clearances, the threshold and adjoining finish will be resolved for the selected assembly. Do not trim, alter or improvise a detail after delivery without the relevant supplier's assessment.
The neatness of the junction should follow an appropriate installation rather than drive an unverified alteration.

7. Define installation and making good
Include dismantling, disposal, delivery, installation, frame finishing and any affected surrounding surfaces. Confirm who handles required applications and associated fire-safety items. HDB identifies fire-rated main-door replacement as fire-safety work associated with home fire alarm requirements.
Have the contractor confirm what applies to the actual scope and keep the responsibilities explicit.
8. Check operation at handover
Have the installer demonstrate closing, latching, locking and any supplied closer or digital features. Check the selected assembly against the order and retain its documents. Record defects or adjustments with the supplier.
Follow the care and maintenance instructions rather than removing or disabling a component because it changes the feel of the door.
A practical planning example
The following is a hypothetical planning scenario. An HDB owner plans a new main door, digital lock and thicker floor finish at the entrance. Ordering them separately risks a mismatch between hardware, leaf preparation and finished clearances.
A coordinated brief gives the door supplier the final flooring detail and selected lock before measurement. The contractor also confirms the flat's applicable door and permit requirements. This example describes a planning sequence; it is not a certification of a particular entrance.
Compare the scope before committing
| Option | When to consider it | What to confirm |
|---|---|---|
| Door leaf only | Retain a suitable compatible frame | Condition, hardware and assembly requirements |
| Door and frame | Replace the complete entrance assembly | Removal and surrounding making good |
| Hardware change | Alter operation or access | Product compatibility and applicable certification |

Frequently asked questions
Does every HDB door replacement follow the same rule?
No. Check the current requirements for the actual entrance and proposed work rather than using a universal assumption.
Can I add a digital lock after ordering?
Confirm the specific lock and door compatibility first, including the relevant requirements where a fire-rated door is involved.
